As Huntsman tries to boost his poll numbers, he hasn’t been shy about criticizing his rivals, especially Mitt Romney and most recently Ron Paul. He released a scathing web video Thursday using Paul’s old newsletters against him.

“I’m not sure it’s negativity. I think it’s just facts out there on the record,” Huntsman argues.

The attacks underscore Huntsman’s most important argument, electability.

“You have to position yourself in a way that suggests you’re electable,” Huntsman says. “Once people see that you’re electable and can go on and beat Barack Obama, as everyone knows I can do, the question is can he make it through the early primaries.”
